CAR-COUPLING.

Specification of Letters Patent.

Patented June 5, 1906.

T at whom it may concern:

Be it known that I, LEwIs C. CARY, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Car-Couplings, of whichthe following is a specification.

My invention relates to car-couplings, and more especially to theautomatic type, and has for its objects, first, to provide an automaticcar-coupling that will always be ready for coupling engagement withoutprevious opening or setting to receive an approaching head; second, toproduce a coupling in which there shall be practically no slack betweenthe heads of the couplings when coupled to avoid the jerk in starting orstopping incident to couplers that are not taut; third, to providemechanism for uncoupling the heads when coupled, and, fourth, to provideimmovable means to prevent lateral movement of the heads when coupled;and to these ends the novelty of my'invention resides in the particularconstruction, combination, and arrangement of parts, as will behereinafter more fully described, and pointed out in the claims. Iattain these objects by the mechanism illustrated in the accompanyingdrawings, in which- 1 Figure 1 is a side view of two heads coupled. Fig.2 is a section on line 2 2 of Fig. 1. Fig; 3 is a perspective view ofone head. Fig. 4 is a perspective of the releasing-heel. Fig. 5 is asection on line 2 2 of Fig. 1, and Fig. 6 is a side elevation brokenaway to show pivotal mounting of the releasing-heel.

Similar numerals refer to similar parts throughout the several views.

6 6 denote the heads of the couplings, which are exact duplicates ofeach other. Each head is provided with two jaws 7 7, triangular incross-section, normally positioned one above the other, with anintervening space 8 between the jaws, and each jaw is provided with aninclined engaging face 9 and with an integral rib 10 on its back and atsufficient angle to facilitate the coupling of cars of variant heightsof coupler positions. Each head is provided with a coupling-lever 11,which is pivotally mounted in the space between the jaws 7 7 and adaptedto effect coupling engagement when the heads are brought together.

11 indicates a coupling-lever the inner end of which is pivoted on shaft12 at the rear of the triangular jaws 7 7, but through the hollowdraw-bar 5.

13 represents the outer end of the couplinglever, which is curvedoutwardly at its free end and extends forwardly and somewhat beyond theends of the jaws for the purpose of guiding the heads into properhorizontal relation when approaching each other for coupling engagement.The coupling-lever 11 in each head is provided with a shoulder 14 forthe purpose of interlocking with the lever in the opposing head. Eachhead is provided with a disengaging device comprising the shaft 15through the rear ends of the jaws in opening 15, the crank 16, and thereleasingheel 17 for the purpose of uncoupling the heads. Thereleasing-heel is pivotally mounted in the rear portion of the spacebetween the jaws. Fig. 5 is a longitudinal section showing couplinglevers 11 11 and heels 17 17 just after rotating cranks 16 16 and shafts15 15 to disengage shoulders 14 14 for uncoupling the heads. One or bothof the release-cranks 16 16 may be turned with sufficient force to pushthe heels 17 17 outward against the forward end of the locking-lever ineach head to disengage the shoulders 14 14 to uncouple the heads. Cranks16 16, Fig. 6, are shown in the positions they would be in Fig. 5 whenheels 17 17 have pushed the coupling-levers 11 11 far enough apart torelease the shoulders 14 14.

17 in Fig. 6 represents the portion of the releasing-heel through whichthe rectangular part of shaft 15 extends. The shaft may be fastened inor to the heel by a key or other suitable means. The shafts are shown tobe round near their ends and rectangular for about the middle one-thirdof the length and as not extending entirely through the lower jaw, butmay be made to extend entirely through the upper and lower jaws and besuitably fastened at its lower end to prevent vertical withdrawal.

Each locking-lever 11 is maintained in looking engagement by an elasticsteel plate 18, suitably fastened, as shown at 19, and bearing upon itsouter surface.

20 represents a jaw-bearing abutment at the rear end of each head and isprovided with bearing-surfaces 21 21 and lateral arms 22 22. The forwardend of each aw is provided with a pushing-surfaceg23 and an extension24. When the heads are being coupled, the extensions 24 24 pass underthe lateral arms 22 22, and when coupled these arms prevent lateralmovement of the heads.

It will be noted the foregoing construction will give equal efficiencywhether cars are pulled or pushed and that it will be impossile tobuckle these couplings. Also no buffer apparatus will be required.

In operation when it is desired to uncouple the heads it is onlynecessary to turn one or both of the cranks 16 to push the heel 17against the forward end of the locking-lever of the opposite head untilthe shoulders 14 14 are out of engagement, when the heads may beseparated.

A great many slight changes might be made in the general form andarrangement of the parts described without departing from my invention,and hence I do not .restrict myself to the precise details set forth,but consider myself at liberty to make such slight changes andalterations as fairly fall within the spirit and scope of my inventionand the protection prayed.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a car-coupling a head comprising two jaws positioned one above theother, with inclined engaging faces, an integral rib on the back of eachaw, means for locking said head to an opposing head and a releasing-heelfor unlocking the heads.

2. In a car-coupling a head comprising two jaws having inclined engagingfaces, an integral rib on the back of each jaw, a jawbearing abutment,means for coupling said head to an opposing head, and a releasingheelfor uncoupling said heads.

3. In a car-coupling a head comprising two jaws normally positioned oneabove the other with inclined engaging faces, an integral rib on theback of each aw, a aw-bearing abutment with lateral arms extendingtherefrom, means for coupling said head to an opposing head, and meansfor uncoupling said heads.

4. In a car-coupling'a head comprising two jaws triangular incross-section and having inclined engaging faces, an integral rib on theback of each jaw, a bearing-abutment near the rear of said jaws withlateral arms extending therefrom, pushing-surfaces on the forward endsof said jaws, means for coupling said head to an opposing head andvmeans for uncoupling said heads.

,two jaws with inclined engaging faces, an integral rib on the back ofeach jaw, a bearingabutment with arms extending laterally therefrom,forward extensions on said jaw adapted to be inserted between saidinclined faces and said arms to prevent lateral movement of the aws, apushing-surface on the forward end of each jaw, a spring-pressedcoupling-lever and a releasing-heel for uncoupling said heads.

7. In a car-coupling a head comprising two jaws normally positioned oneabove the other with inclined engaging faces, en integral rib on theback of each jaw, a bearing abutment with arms extending laterallytherefrom, a spring-pressed pivoted couplinglever for coupling said headto an opposing head, and a releasing-heel for uncoupling said heads.

In testimony whereof I afiix my signature in presence of two witnesses.
